How do we get out of this way, so we can respond to the damage to sonny's laptop? This requires us to learn how to fix sony's notebooks, which today brings to you several of the more common patterns of damage and how to fix it, in the hope that you will learn to do so。
I. System overheating
The laptop is frequently used in a dead machine, and the temperature is felt at the bottom。
The laptop space is small and the heat is not good. It is easy to accumulate the heat that is released from the various components, resulting in abnormal computer work and even burning the machine. Thus, in the use of laptops, since they are usually heat-dispersed through the bottom and side, the first is to avoid prolonged use in high temperatures; second, it would be preferable not to use too soft a platform, which would be detrimental to the spread of heat. The laptop must be placed on a well-ventilated hard plane, while the laptop is regularly cleaned, the dust removed, the air flow of the vent is smooth and the system is ventilated。
Some of the processes requiring a * processor will result in a certain increase in the temperature of the laptop, which will automatically slow down the cpu to protect it from high temperatures。
If the laptop is operating at a very high temperature, the power should be shut down after the file is kept quickly and the working environment replaced. If the above problem still arises, the laptop is sent to the department of professional maintenance for testing。
It should be noted, in particular, that the use of desktop cpu laptops, which are used for long periods of hot summers, makes it highly likely that death machines will occur. It was strongly recommended that, for users with higher stability and better economic conditions, it would be preferable not to choose such laptops。
Power failure
As an important demonstration of mobile office, the power system in laptops is an important and vulnerable component。
Battery damage. The battery is “aging” after a certain period of time of use, in the form of greater internal resistance and a faster increase in both ends of the voltage when charged. This is easily judged by charging control lines to be already full, with natural decreases in capacity. Because of the relatively high internal resistance of batteries and the large and rapid decrease in voltage during discharge, the system is prone to misperception that the voltage is insufficient and the amount of electricity is insufficient. In short, battery ageing is a vicious process. When battery hours are found to be shorter, appropriate measures should be taken。
In addition, a lot of lithium batteries fail because of the failure of one of the energy cores in the battery pack, which is inevitable. Since the core properties of each battery cannot be fully consistent, some of the lower quality begins to age over time, destroying the discharge curve of the whole (after a string). An interested and capable reader can try to open a battery bag, and with the help of a universal watch, you can quickly find the damaged core. If conditions permit, replacement of the eligible crystal with the corresponding parameters for the core is sufficient。
Maintenance and restoration. The process of maintenance and restoration of the batteries is also referred to as “activation” or “activation”, and the basic principle of activation of a battery is that the current must be small when charged (too small would result in excessive duration) and be as full and complete as possible。
3. Filling. Lithium ion cells start with a constant current and are charged slowly at constant pressure when the voltage reaches a certain value. When the system is loaded up, the chargeable current is small, and vice versa, and the current is determined by the power surplus of the ac power adaptor. It is clear that batteries will compete with other components such as cpus, hard drives and lcds when the system is charged. The author tried to run super while charging it, and found that the charging current varied between 0. 70 a ~ 1. 70 a and did not meet the recharge requirements for lithium ion batteries, so that the charge-up would damage the battery during the operation. This may also be the reason why ibm laptop instructions require batteries to be charged without performing other operations。
Iii. Lcd failure
The failure of the laptop's lcd is mainly due to the failure of people who hit, pressed or fell during their use, causing the monitor to have a lot of bad points, colours, broken panels, and even no images at all. Such failures are difficult to repair on their own and are usually handled by professional maintenance staff. It is easier to deal with problems caused by poor or fractured signal lines of the lcd and the mainframe. If the lcd itself is damaged, only replacement is available. The price of lcds varies depending on the machine type, ranging from 30 to 50 per cent of the total cost。
In addition, in general, the membrane field effect transistors (i. E. Tft lcds) of laptop computers contain up to 2 million field effects tubes. It is precisely as a result of the process of production of this technology that a certain amount of pixel failure (including loss of pixel points, or loss of pixels colour, or failure of pixel lights) is a characteristic of the membrane effect tube crystal screen technology. This is inevitable for any producer。
These are the more common phenomena of damage to sony's laptops and the methods of repairing them. Do you not know how to do this? Indeed, the above methods are easier to repair. As long as you can look and learn with your heart, nothing can be hard on us. In fact, the most important thing in the computer repair process is that we can find the source of the damage, so long as we can fix the source of the damage, so many minor problems with the sony laptop will be solved。
